-iECTRIC REGISTERING SYSTEIYI.

To all whom it may concern Be it known that I, HENRY Hovmnn, a citizenof the United States, residing at East Orange, in the county of Essexand State of New Jersey, have invented certain new and usefulImprovements in Registering. Systems. of which the following is a full.clear,

concise. and exact description.

This invention relates to registering and recording mechanism. moreparticularly for registering mechanism which may he employed intelephone systems.

The object of this invention is the provision of means which willaccurately register or record signals resulting from rapidly re curring;current impulses.

ln accordznice with the general features of this invention there areprovided two sets ot relays responding to the current impulsesconstituting the signals. one set oi said relays being designed andadjusted to release quickly and adapted to release upon the break of theimpulse circuit; the other set of relays being designed and adjusted toenergizo very rapidly and connected in circuit to operate from theclosure of the circuit. These sets of relays control the operation of agroup of controlling relays, which group of relays in turn control thesetting of the registering and recording deto the means which controlsthe setting ofthc registcriiur mechanism.

An impulse transmitter suitable for use in the ])I'&"'-2l' system isdisclosed in applicants Patent. o. 1,271,164. issued July 2, 1918.

The wgistcrin or recording mechanism which will hereinafter be referredto as the and which is generally designated the drawing, consists of avshaft 1 Specification of Letters Patent.

mounted in any suitable manner for rotation. At one end of this shaftand extendin; at right angles thereto, there is secured an arm 2 which.when unrestrained. moves in a clockwise direction under the control ofthe spring 3. The arm 2 is held in its normal position by a latch member4 pivotally mounted at the free end of the arm 54. The latch. member-lis normally held. in alinement with the arm by av spring member. Thislatch member is provided with an arm 5, which engages a hook (3 of thearmature ot' the magnet: 86 to hold the arm 2 in its normal position.For controlling the setting of the arm 2 there are provided five rodsEach of these l'()(l is substantially similar in structure andoperation. so it will only be necessary to describe. the structure.mounting, and operation of one rod, for example, the rod 12. The rod 1:2is mounted for rotation in any suitable manner, and near one of its endsis provided with a. riulit1-angular pin 13. This pin operates in thebi-- fureated extension of the pivoted armature 14-, which is mountedfor actuation under the control of either of the magnets 15 or 16. \Vhcuthe magnet 15 is eueip'ized it attracts its armature to move the pin 13in a downward direction. This causes the rod 12 to rotate in acounter-clockwise direction. \Vhen. however, the magnet lt is encr ized.it attracts its armature to more the pin 13 in an upward direction. Thiscauses the rod 12 to be moved in a cloclnvise direction, as indicated bythe arrow. The rod 12 is provided with a plurality of stops. two f reach register: these stops areindicated at l7 and 19. It will be notedthat stops 1? and 1 are out. of alinement. An :ll'(-filltl}7etl menu her19 provided with ratchet teeth on its inner surface is ciug'a red by dog20 on the latch member l to hold arm 2 in actuated position as will befurther described in the operation of the system.

Mounted on the shaft 1 of the register. there are secured a. pluralityof contact con trolling devices of the structure and arrangement of thesequence switch disclosed designated 8, 9. 10, 11 and 12. e

indicated at 102,

inv the patent to Reynolds and Baldwin 1,127,808. These contact elementsof the registers R R and R are diagrammatically 103 and 104,respectively. These registers may be restored by power driven means asin the above noted patent.

With this brief description of the apparatus it is believed that theinvention will best be understood by setting up a number on. theregisters shown. Let it be assumed that the desired number which istransmitted from the dial switch at the substation apparatus is thenumber 109. When the subscriber removes his receiver from theswitchhook, the hook-switch springs 21 and 22 are closed. As soon as thereceiver is removed from the switchhook, the line finder wnich indicatedby the brushes 2? and 28 is operated in the well-known manner to seizethe terminals 29 and 30 of the calling line. As soon as the calling linehas been Located, a circuit is completed from ground, through thewinding of the relays 23 and 24 in parallel, conductor brush 28,terminal 30, switchhook springs and 21, contact 31, shunting spring 32,transm'ittcr winding of the induction coil 34. impulse spring contact36, terminal 25! of the calling line, finder brush 2?, armature and backcontact of the cut-off relay 38, armatures and back contacts of therelays c c c c 0, 0, 0 w, 0", lower winding of relay 40, t0 groundedbattery, where upon relays 23, 24 and 40 are energized.

Al the rigl'it-hand contactand armature of the relay acircuit is completed from ground, conductor 41, armature and backcontact of relay 42, winding of the relay 43, to grounded battery. Therelay 43 attracts its armatures and at its left-hand armature and frontcontact completes a circuit from ground, conductor 44, right-handarmature and back contact of relay C", right-hand Winding of relay 0, togrounded battery, and similar parallel circuits are com lcted throughthe right-hand armatures am back contacts of the relays C", C", C and C.to grounded battery, through the.

right-hand windings of relays 1;, c c", r;,

0", c 0 c. The last-mentioned relays are energized in these circuits.

As soon as the dial D is moved, the circuit through contact 31 andshunting spring 32 is opened, and a circuit is compteml through contact45 and shunting spring 32. The closing of the circuit through contact 40and shunting spring 32 includes the resistance 46 in the energizingcircuit of the relay 23. The relay 23 is marginal and does not rcmamenergized in series with resistance 46. When the dial is moved farther,the circuit completed through the contact 36 and spring 35 is opened,but the relay 24 is slow to release and does not dcenergize during themomentary interruptions of its operating circuit. The dei nergization ofrelay 23 causes relay 38 to release and also causes the shunting circuitabout relay 42 to be broken. The relay 42 is energized over a circuitextending from grounded batter windings of the relays 43 and 42,right-hand contact and armature of the relay 43, front contact andarmature of relay 24. to ground. WVhen, in the operation of the dial,the spring 35 engages the contact 36, a circuit is closed from ground,winding of relay 23, conductor 25, finder brush 28, terminal 30,switchhook springs and 21, resistance 46, contacts 32 and 45, springcontact 36, terminal 29, brush 27, armature and back contact of cut-offrelay 3S, armature and front contact 01 relay c and winding of thisrelay to grounded battery and in parallel through the left-hand windingof the relay C to grounded battery. Relay C attracts its armaturcs andat its right-hand armature and back contact interrupts the holdingcircuit of the relay 0. Atthe righthand contact and armature of relay aholding circuit is closed for this relay which may be traced from groundat the leftehand armature and front contact of relay 43, conductor 44,right-hand armature and front contact of relay C, contact 62, spring 61,resistance 93, to grounded battery. Since the relay is marginal it willnot energize while resistance 46 is connected in this opcrating circuit.When now the dial is operated to again interrupt the circuit throughcontact 36 and ix'npulse spring 35, relay n will retract its armatureand at its back contact will extend this circuit to the relay 0'. At theclose of the series of the. impulses corresponding to the first digit,the dial will return to its normal position to close the contact 31 andshunting spring 32.

\Vith the contact 31. and shunting spring 32 in engagement, theresistance 46 is shuntcd from the operating circuit of the relay 23,causing this relay to energize. The. relay 23 attracts its armatures andcompletes a circuit from ground, its right-hand armature and frontcontact, conductor 41, armature and front contact of relay 42, contacts20 and 47, winding of relay 48. to grounded battery. Relay 48 attractsIts armatures and com'nlctra a l\) 'iiiz|.f circuit for i sel from its(1 c c, c and c are menses front contact and left-hand armature over theremainder of the circuit just described. l Vhen. the relay is energizedcircuit is completed from grounded battery, arnni'l'ure and Contact d9of this relay, Winding of relay 50, conductor 51, leithand armature andfront contact of relay (1*, ture and back contact of relay C, conductor44-, left-hand front contact and n-rnniture of relay 43, to ground, whenrelay fill is energizecl, to rotate the rod M in a cloc Wise direction.The arnuiture of magnet 50, in operating, closes a circuit from ground,spring 52 and its contact, conductor 53, Winding of nnignet 55, contact50, righthand armature oi. relay 48, to grounded battery.

Al the left-hand front contact and arimiturcoi relay the energizing circuit of magnel if) is opened, causing thismagnet to dci ncrgizc and pcrmit the roll 54 to return to its normalposition. Vihcn the rod returns to its normal position, the energizingcircuit of magnet 55 is opened at contact spring to cause the magnet 55to dei nergize. When the magnet 55 deiimergizes, the contact spring 58discngages its contact to open the energizing circuit of the relay 60.At the time that the relays C and decnero'izcd they completed circuitsat their right-hand armaturcs and back contacts for rei ncrg'izingrelays c and c.

The relay 23 at its right-hand armature and front contact interrupts theactuating circuit of relay 48, allowing it to release. When now, theimpulse spring 35 engages its contact 36 the relay C will be energized.

n releasing the dial, shunting spring 32 will engage its contact 31, toshort-circuit the resistance 16, and cause the relay to operate. ItWillbe remembered that the register R is in position 1. lVilh the reg-isfor R in position 1 and relay 23 energized a. circuit is completed fromground, conductor 41, armature and front contact oi rclav -12, armatureand back contact of relay contacts 64 and (55, contacts 67 and 6h,winding of the relays 69, to grounded lmttcry.

Relay ($0 when it attractsits arn'iaturc causes the decnerg'ization of any of the relays (l to Cwhich have been actuated. When the relay C retracts its arn'iature, theenergizing circuit of the ma netiG is interrupted, causing this magnetlo retract its armature, thus permitting the rod 75 to return to normal.

The subscriber now sends lhc ncxl scries of impulses corrcspomlingr tothe units digit. which in the case assumed is 9. Tu response to each ofthese impulses a relay correspoluling lo the relay C" is energized andlocked up, while a relay corresponding to relay 1 is dci uernizcd. At (htermination of the line iu'ipulses the relays C to (,l

and relay ll) will be actuated and locked up and the relays c to 0 willbe deenergiaed. Wl'ien now the resistance M3 is shunted from theoperating circuit of the relay 23, a circuit is completed. from ground,right-hand armature and front contact of the relay i 33, conductor ell,armature and front contact of relay lii, armature and back contact ofrelay 48, contacts 6% and 65, armature and back cont-act of the relay69, contacts and 81, contacts 82 and 83, winding of the relay 8%, togrounded battery.

Magnet 15 is energized in thiscircuit. Magnet 15 rotates the rod 75 in a clockwise direction to setthe stop 88. T he armature of magnet 15 is operated and closes a circuitfrom ground, spring 89 and its contact, conductor 90, winding of magnet86, contact 91, right-hand armature of relay Sl to grounded battery. Themagnet 86 is energized and unlatches the arm 2 of register R permittingthis arm to rotate until it engages the stop 88.

Relay 0 attractsits armature and at the contact spring 62 interrupts the holdingcircuits of the relays C to U" It will be understood that as manyregisters of the type of register R will be employed as there are digitsin the desired number. For registering a number of more than threeunits, it will only be necessaryto increase the number of registers andlengthen rods 8 to 12 and provide them with the necessary stops for eachregister. In the description of this invention it has been deemednecessary only to describe the setting of the registers. In the employment of this invention in a telephone sys' tem after the registers havebeen set they may be used to govern the operation and setting ofcounting relays, which in turn control the setting of automatic switchesin the manner clearly shown and described in the patent to A. E.Lundell, 1,168,819. V7 hen it is desired to erase the number registeredthe subscriber replaces the receiver on its switohhoolr. This causes theseparation of the switchhoolr springs 52?. and 22 and, in turn, thedeenergisation of the relay Relay on deenergizing at its front contactand armature interrupts a circuit which maintained the relay l3energized. The relay -13 at its left-hand back contact and ari'naturecloses a circuit from ground, conductor 94;, contact 95, winding of themotor magnet 96 to grounded battery, and in parallel through contact 97,winding of motor magnet 98 to grounded battery, and contact 99, windingof the motor magnet 100 to grounded battery. The motor magnets operatein the manner of the sequence switches to restore the registers R, R andR to their normal posilion, in which they will be held by book 6.
